Formation of submillimeter liquid‐encapsulated gas bubbles in an immiscible liquid

摘要: A simple device is described which enables a steady formation of small ‘two-phase bubbles’ each consisting core gas and shell liquid immiscible with the surrounding liquid. The essentially fine double-tube nozzle permits parallel feedings to its tip having particular configuration. It has been found that successfully releases into pool pure water, liquid-fluorocarbonencapsulated bubbles uniform diameter less than 1 mm. function lost, however, when water contaminated surfactants. may be applicable some extraction processes whose efficiency should increased by producing liquid-encapsulated bubbles.
